Kryptolok called milled and heat-treated petroleum coke. Kryptol used in electrical furnaces as electric resistances.
Cryptologie baths, and cryptologie oven, allow to reach very high temperature up to 2000 C.
Kryptol forms of non-volatile, non-conductive oxides. Therefore, the acceptable electrical contact resistance between the pellets stored at any temperature and degree of oxidation of Kryptol.
The electrical resistance of the volume filled with cryptolog, is large compared with the resistance of monolithic graphite. This gives you the opportunity to nourish cryptologie furnace is simpler and cheaper sources of supply.
